DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0101] Preferable embodiments of the present invention will be explained in more detail with reference the attached drawings.

Digital Broadcast System

[0102] For broadcasting audio and video data, the digital satellite broadcasting services rely on a MPEG2 technique which broadcasts a transport steam (TS) including a plurality of multiplexed packets of audio and video data. Besides the audio and video packets, the transport steam (TS) includes program information (i.e., program information required for multiplexing the audio and video information formatted according to MPEG2 and DVB). The program information is described in the form of a section-type table.

[0103]FIG. 73 shows a digital broadcast system including a broadcast center system 1000. In FIG. 73, the broadcast center system 1000 comprises an audio/video stream producing system 1001, a program information producing apparatus 500, and an encipher key management and producing system 1003 which separately connected to a TS multiplexer 1004. An uplink system 1005 transmits a produced TS signal in the form of radio wave to a satellite 1006.

[0104] An audio/video and program information organizing system 1002 produces and stores program schedule information. The program information producing apparatus 500 receives the program schedule information from the audio/image and program information organizing system 1002, and produces program information (including program information used for multiplexing audio and video information and additional program information used for producing a program guide).

[0105] The audio and video data is sent from the audio/video stream producing system 1001 to the TS multiplexer 1004 in accordance with the program schedule information stored in the audio/video and program information organizing system 1002. The produced program information is multiplexed with the audio and video data in the TS multiplexer 1004. The multiplexed signal is sent to the uplink system 1005 and received via the satellite 1006 by each home receiving apparatus 100 associated with a TV monitor 10.

[0106] When the receiving apparatus 100 receives a PPV (pay per view) program, charge information is sent via a public network 1007 to a charge information collecting system 1008 of the broadcast center system 1000. The encipher key management and producing system 1003 allows the viewing of the requested PPV program upon confirming the procedure in the charge information collecting system 1008.

[0107] Hereinafter, preferable embodiments of the present invention will be explained with reference to attached drawings.

First Embodiment

[0108] A first embodiment of the present invention provides a system capable of searching programs according to user's preference, and producing and displaying a “my channel” consisting of programs fulfilling the search conditions (e.g., fee) given from the user.

[0109]FIG. 1 shows a receiving apparatus 100 including a receiving section 1 which receives program information shown in the upper part of FIG. 3. The received program information is sent to a program information storing section 2. A search condition input section 3 gives a search condition, such as “a program fee is not higher than 100 yen.” A program information processing section 5 receives the program information from the program information storing section 2. A program information search section 4 searches the program information in the program information processing section 5 and selects programs fulfilling the search condition given from the search condition input section 3. Thus, as a result of the performed search, the program information search section 4 produces personalized program information comprising the selected programs fulfilling the given search condition.

[0110]FIG. 2 shows the algorithm of the program search processing and the program information producing processing performed based on the search result in accordance with the first embodiment. More specifically, all programs described in the program information are sorted by order of start time (in step S101). Then, it is checked whether the sorted program is present or not (in step S102). When no sorted program is present (NO), this routine ends. When any sorted program is present (YES), it is then checked whether the given search condition is fulfilled or not (in step S104). When the search condition is not fulfilled (NO), the processing of the next program is started (in step S103) and the processing of the step S102 is performed again. When the search condition is fulfilled (YES), the information of the sorted program is added to a program list of the searched program information (in step S105). Then, the processing of the next program is started (in steps S103 and S102) as described above. When no sorted program remains, this routine ends.

[0111] Through the above-described program search processing, the program information search section 4 produces the program information comprising the programs fulfilling the given search condition, as shown in the lower part of FIG. 3. FIG. 4 is a program guide displayed through a program guide display section 6. For example, a “my channel” shown in FIG. 4 comprises a program {circumflex over (1)} (having a program number 101 selected from the service channel “Nihon Maru” shown in the upper part of FIG. 3), a program {circumflex over (5)} (having a program number 202 selected from the service channel “Fuji Sun”), and other programs starting after 15:00 which are selected in the same manner from the received service channels. The “my channel”, including the personalized program information resulting from the search processing, is displayed in the lower part of FIG. 3. In other words, the “my channel” is a user's personal channel not described in the program information received by the receiving section 1. The obtained “my channel” constitutes one channel of the program guide shown in FIG. 4.

[0112] When the viewer selects the “my channel” from the program guide, a tuning switch section 33 tunes in to a presently broadcasted program of the “my channel.” A program display section 8 displays the program. For example, it is assumed that the “my channel” is selected at 13:00. According to the program guide shown in FIG. 4, the tuning switch section 33 immediately tunes in to the program {circumflex over (1)} of the service channel “Nihon Maru”, and subsequently at 14:00 tunes in to program {circumflex over (5)} of the service channel “Fuji Sun.”

[0113] In the algorithm of the program information search, the search is performed only for the programs whose start times are equal to or later than the end time of the program added to the list of the searched program information. For example, when a program ending at 14:00 is added to the list of the searched program information, no search is performed for all of programs having start times earlier than 14:00 and the search is performed for the programs having start times equal to or later than 14:00.

[0114] Furthermore, when the program information shown in the upper part of FIG. 5 is received, a search condition “a program fee is not higher than 150 yen” may be entered. In this case, the program information shown in the lower part of FIG. 5 is produced as personalized program information resulting from the search. The resultant program information is displayed through the program guide display section 6, as shown in FIG. 6. In this case, the program guide displays two channels of “my channel 1” and “my channel 2” because a total of two programs are scheduled in the same time slot from 15:00 to 16:00. The “my channel 1” includes a program {circumflex over (10)} of the service channel “Asahi”, while the “my channel 2” includes a program {circumflex over (6)} of the service channel “Fuji Sun.”

[0115] According to the tables shown in FIGS. 4 and 6, the user's personal “my channel” is an independent channel. However, as shown in FIG. 9, it is possible to display the “my channel” consisting of the selected programs using colors or fonts discriminable from non-selected programs.

[0116] Furthermore, the above-described search condition relates to the program fee. It is however possible to use a search condition relating to other factor, such as program genre, viewer's residence, sex, age or the like. It is also possible to use other search conditions occasionally entered from the viewer or adequately judged from viewing history.

[0117] It is also preferable to use a program guide shown in FIG. 10, according to which the fee for each PPV program is displayed and a total fee (i.e., a sum amount of charging fees) is displayed separately. Regarding the display for the total fee, it will be possible to use various graphic techniques, such as a bar graph or a color display.

[0118] As apparent from the foregoing description, the first embodiment of the present invention makes it possible to display a program guide including a personal channel consisting of the programs selected according to the search condition given from the viewer. This arrangement is helpful for the viewers in selecting favorable programs from numerous programs receivable by his/her receiving apparatus. Furthermore, as an independent channel is assigned to the searched programs, the viewers can continuously watch the favorable programs without changing the channel. Providing the display of program fees is effective to facilitate the program selection. Thus, the first embodiment of the present invention improves the conspicuousness of the program guide.

Second Embodiment

[0119] A second embodiment differs from the first embodiment in that, when the viewer selects any program not included in the list of the searched programs, the search is performed again so as to include the designated program.

[0120] It is assumed that, when the program guide of FIG. 4 is displayed, the viewer manipulates a remote controller 9 to change the “my channel” so as to include a program 11 of the service channel “Asahi.” in response this request, the program information search section 4 performs the search according to the algorithm shown in FIG. 7. More specifically, all programs described in the program information are sorted by order of start time (in step S111). Then, it is checked whether the sorted program is present or not (in step S112). When no sorted program is present (NO), this routine ends. When any sorted program is present (YES), it is then checked whether the sorted program is the designated program or not (in step S114). When the sorted program is the designated program (YES), the information of the sorted program is added to a program list of the searched program information (in step S117). Then, the processing of the next program is started (in steps S113). Then, the processing of the step S112 is performed again. When the sorted program is not the designated program (YES), it is then checked whether the sorted program and the designated program are in the same time slot or not (in step S115). When the sorted program and the designated program are overlapped (YES), the flow of this control routine proceeds to the step S113 and then returns to the step S112. When the sorted program and the designated program are not overlapped (NO), it is then checked whether the given search condition is fulfilled or not (in step S116). When the search condition is not fulfilled (NO), the processing of the next program is started (in step S113) and the processing of the step S112 is performed again. When the search condition is fulfilled (YES), the information of the sorted program is added to the program list of the searched program information (in step S117). Then, the processing of the next program is started (in steps S113 and S112) as described above. When no sorted program remains, this routine ends.

[0121] As a result, the program guide display section 6 displays a program guide shown in FIG. 8 which differs from the program guide shown in FIG. 4 in that the “my channel” includes the program 11 of the service channel “Asahi” in the time slot from 16:00 to 17:00. In other words, the program {circumflex over (7)} is replaced by the program 11.

[0122] As apparent from the foregoing description, the second embodiment of the present invention allows the viewer to modify the program guide through a manual operation when the program guide does not include any favorable program. Thus, it becomes possible to reschedule the personal channel.

Third Embodiment

[0123] A third embodiment of the present invention provides a system which is responsive to viewer's selection of a time shift program and performs the scheduling so as to mandatorily include the designated time shift program. When there are a plurality of patterns, display of these patterns is performed by order of fee.

[0124] The “time shift program” is generally referred to as a program repetitively broadcasted in different time slots. According to the third embodiment, the viewer selects a favorite program from a time shift program list shown in FIG. 11. In this case, each time shift program has a fee variable according to the broadcasting time. For example, the viewer may select a program “guide to C++” as a favorite time shift program. When the viewer selects a “start scheduling” key displayed on the screen, the program information search section 4 shown in FIG. 1 performs the scheduling and produces the searched program information (FIG. 14). The program guide display section 6 displays a program guide shown in FIG. 12, highlighting the search programs corresponding to the search ID=1 shown in FIG. 14. The total fee for the selected programs is 800 yen. When the viewer selects a “next route” key displayed on the screen, the program guide display section 6 displays another program guide shown in FIG. 13, highlighting the search programs corresponding to the search ID=2 shown in FIG. 14. Both of the program guides shown in FIGS. 12 and 13 include the program “guide to C++”, but the latter is more expensive in the fee than the former. When there are three or more candidates, the similar operation is repeated. Thus, the viewer can make a reservation of viewing or recording by checking the contents of the plurality of routes.

[0125] It is possible to select a plurality of programs, although only one program is selected in FIG. 11. In this case, the program information search section 4 shown in FIG. 1 performs the scheduling so as to include all of the designated programs. If it is impossible to include all of the designated programs, a message display informs the viewer of failure of the scheduling. The message may include a statement that the scheduling is feasible upon reducing the number of programs.

[0126] Although the above-described embodiments discloses the receiving apparatus having the receiving section for receiving the program information, it is possible to use other media, such as FD and DVD, for storing and transmitting the program information, or it may be possible to use a terminal having the capability of storing the same.

[0127] In the explanation of the above-described embodiments, operation of the broadcast center is omitted. However, it should be understood that the program information is produced from the program schedule information sent from the audio/video and program information organizing system 1002 shown in FIG. 73. If the audio/video and program information organizing system is not provided, it will be possible to produce the program information from the program schedule information in the program information producing apparatus.

[0128] In the display of both program guides shown in FIGS. 12 and 13, the selected programs are highlighted by changing the color. However, it is possible to provide an independent channel in the same manner as that of the first and second embodiments.

[0129] As described in the foregoing description, the third embodiment of the present invention allows the viewers to select a preferable program schedule among a plurality of routes considering the charging fee or viewer's personal schedule, for example, when the viewer has preferable programs in mind but has not yet fixed the schedule. Thus, it becomes possible to reduce the burden of the viewers in the selection of programs.

Fourth Embodiment

[0130]FIG. 26 is a block diagram schematically showing the arrangement of a program information producing apparatus 500 in accordance with a fourth embodiment of the present invention. The program information producing apparatus 500 comprises an advertisement information producing section 53 which produces a packet ID (PID) of each elementary stream (ES) of advertizement audio and video data to be involved in the program. FIG. 15 shows the program information including the packet IDs of the advertisement elementary streams. In other words, an advertisement stream data base 54 sends out the audio and video data of the advertisement stream in the form of PID described in the program information.

[0131] A receiving apparatus 100 shown in FIG. 27 refers to the program information and does not decode advertisement streams even when the selected channel agrees with viewer's preference. More specifically, the program display section 8 decodes only the audio and video data of ordinary programs other than the advertisement streams, and displays the decoded video with sounds through a TV monitor 10. FIG. 16 shows the screen of TV monitor 10 only displaying the elementary streams of packet IDs 122 and 455 in accordance with the program information shown in FIG. 15. However, decoding the audio and video data of the advertisement streams of packet IDs 200 and 788 is feasible in response to the request of the viewer. FIG. 17 shows a program guide with a portion “A” displaying the advertisement data. Besides the audio and video data, it is possible to provide an advertisement steam of text data (as indicated by packet ID 199 in FIG. 15). It is possible to provide a “CM information” key displayed as part of the program guide so as to allow the viewer to display sponsor's statement “C” on the screen. Other data preferably broadcasted in the form of the advertisement stream are still video, sponsor's logo, URL of Internet home page, and sponsor name. In this case, it is possible to provide button keys on the displayed program guide so as to allow the viewer to selectively display the necessary information according to viewer's preference.

[0132] Although this embodiment discloses the program information producing apparatus describing the advertisement streams discriminable in the program information, it is possible to describe the type of the elementary stream in event information.

[0133] It is also preferable that the program information producing apparatus defines numerous advertisement streams, e.g., a plurality of streams for each of audio and video data, and the program display section 8 selects a preferable stream according to the viewer's residence, age and program type (data broadcast, HDTV, SDTV etc.) in the receiving apparatus 100 shown in FIG. 27.

[0134] It is preferable that the advertisement stream storing section 62 stores the advertisement streams received by the receiving section 1. It is also preferable to use other media, such as FD and DVD, to store and transmit the advertisement data. It is also preferable that a predetermined number of advertisement streams are prepared beforehand in the receiving apparatus.

[0135] With the above-described arrangement, it becomes possible to display the sponsor's statement or CM together with the program guide on the screen of the TV monitor 10. If the viewer requests the display of program guide during the broadcasting of CM, the displayed program guide will overlap with the CM at least in part. This embodiment eliminates such sponsor's worries. This is advantageous for the broadcasters when sponsor fees are chief income.

Fifth Embodiment

[0136] According to a fifth embodiment of the present invention, the receiving apparatus 100 has the program guide display section 6 and the program display section 8 cooperatively capable of reducing the size of the program video in response to a viewer's request and displaying the program guide in a newly given space on the screen.

[0137] This embodiment allows the viewer to watch the program guide without interrupting the viewing of the program. In other words, displaying the program guide does not substantially reduce the viewer's chance of watching advertisements. This is preferable for the broadcasters and sponsors because their advertisement activities are not disturbed by the viewer's selection of the program guide.

Sixth Embodiment

[0138]FIG. 28 is a block diagram showing the arrangement of a program information producing apparatus 500 in accordance with a sixth embodiment of the present invention. The program information producing apparatus 500 comprises an advertisement information producing section 53 which produces the program information including advertisement information, such as sponsor ID and sponsor name, as shown in FIG. 20. FIG. 29 is a block diagram showing the arrangement of a receiving apparatus 100. A program information storing section 2 sends only advertisement information to an advertisement information storing section 13. FIG. 22 shows a program guide including both of program names and sponsor names, displayed on the screen of a TV monitor 10. For example, a sponsor name “Umeshita Electric” and a program name “Alarm clock TV!” are displayed in the same program frame of the channel 30.

[0139] Although only one sponsor name is displayed for each program, it is possible to display a plurality of sponsor names for each program. The sponsor information may include sponsor residence, telephone number, URL of Internet home address, sponsor logo data.

[0140] Although the sponsor name and related program name are paired in the same frame of the program guide shown in FIG. 22, it is possible to display video or text data in a predetermined region of the program guide so as to correspond to a related program. Furthermore, it is possible to display animated program.

[0141] The sponsor information may include a service type. It is possible to display the service type together with the program name in the same program frame. .

[0142] As described above, the sixth embodiment of the present invention makes it possible to provide the program guide capable of displaying a sponsor name paired with a program name. This is preferable in that displayed program guide does not substantially reduce the viewer's chance of watching sponsor name or sponsor information.

Seventh Embodiment

[0143]FIG. 21 shows sub programs, such as commercial (CM) and program preview, constituting dissected portions of a program. In the following explanation, a sub program of commercial (CM) will be explained.

[0144]FIG. 30 is a block diagram showing the arrangement of a program information producing apparatus 500 including a program information producing section 50 producing program information and a CM information producing section 55 producing CM information. FIG. 23 shows an example (i.e., event information) of the program information describing program names and broadcast times as well as CM reference information (i.e., CM_ID) involved in the CM information, produced by the program information producing apparatus 500 of the seventh embodiment. FIG. 24 shows an example of the CM information describing CM discriminating information (CM_ID) and CM positional information (broadcast time etc.).

[0145]FIG. 31 is a block diagram showing the arrangement of a receiving apparatus 100 including a receiving section 1 receiving the CM and related CM information and a CM information storing section 16 storing the received CM information. A CM recording managing section 15 uses a CM recording management table (refer to FIG. 25) to manage the CM and the related CM information and further to record (store) the CM. File IDs included in the CM recording management table (FIG. 25) are dependent on a filing system of the storing apparatus in the receiving apparatus 100. Each stored CM is reproducible in response to entry of the corresponding file ID.

[0146] When the viewer requests tuning in to a program, the receiving apparatus 100 decodes the audio and video data of the designated program in accordance with the program information. The decoded video is displayable with sounds through a TV monitor 10. It is assumed that the viewer requests the display of program guide when the TV monitor displays the program. In this case:

[0147] {circumflex over (1)} A CM search section 17 obtains the CM reference information (CM_ID) of the presently display program from the program information stored in the program information storing section 2. For example, according to the program information shown in FIG. 23, the obtained CM_ID is 135 when the program “Alarm clock TV!” is displayed.

[0148] {circumflex over (2)} The CM search section 17 accesses the CM recording management table managed by the CM recording managing section 15 to search or retrieve a CM having the same CM_ID. According to the CM recording management table shown in FIG. 25, the obtained information as a result of the search is a CM named “Goodby” having the CM_ID=135 and file ID=567.

[0149] {circumflex over (3)} The program guide display section 6 provides a space for displaying the CM searched through the procedure {circumflex over (2)} on the same scree as the program guide (refer to “A” in FIG. 17). Sounds may be produced together with the video of the CM. The display pattern shown in FIG. 17 can be replaced by another display pattern shown in FIG. 18 which provides a “CM information” button displayable at a predetermined position on the screen of the program guide. The “CM information” button allows the viewer to get sponsor statement.

[0150] Although FIG. 24 shows the table of CM information, it is possible to use a code indicating that the CM is presently broadcasted. This code, constituting part of the audio and video data of the CM, can be broadcasted together with CM_ID (for example, by describing it in a user data region according to the standard of MPEG). It is preferable that the receiving apparatus receives such a code and performs the recording and management of the CM according to the received code. Although the CM reference information is used to refer to the CM included in the program, the CM reference information may include another CM not related to this program.

[0151] Although a program refers to only one CM in the above-described example, it is needless to say that the number of CMs for a program is not limited to only one.

[0152] Although the above-described example shows a program referring to a sub program, it is preferable that a program refers to other program. In other words, each CM can be defined as an independent program rather than part of a program. In this case, the program information includes both of programs and CMs described in the same manner but discriminable by their ID information.

[0153] According to the above-described fourth to seventh embodiments, the advertisement information or CM information are independent from or part of the program information. It is possible to transmit them separately, or as part of program information, from the program information producing apparatus. The receiving apparatus can operate appropriately in both cases. More specifically, when the receiving section receives the advertisement (or CM) information separately, the advertisement (or CM) information is directly sent to the advertisement (or CM) information storing section. When the receiving section receives the advertisement (or CM) information as part of the program information, the program information is once stored in the program information storing section. Then, the advertisement (or CM) information is sent from the program information storing section to the advertisement (or CM) information storing section.

[0154] Although the above-described examples disclose the advertisement (or CM) information, it is needless to say that the receiving apparatus can handle any other information relating to a program.

[0155] According to the above-described fourth to seventh embodiments, the receiving section of the receiving apparatus receives the program information, CM information and CM. However, it is possible to use other appropriate media, such as FD and DVD, for storing or transmitting the program information and others, or it may be possible to use a terminal having the capability of storing the same.

[0156] In the explanation of the above-described fourth to seventh embodiments, operation of the broadcast center is omitted. However, it should be understood that the program information is produced from the program schedule information sent from the audio/video and program information organizing system 1002 shown in FIG. 73. If the audio/video and program information organizing system is not provided, it will be possible to produce the program information from the program schedule information in the program information producing apparatus.

[0157] As apparent from the foregoing description, the seventh embodiment of the present invention substantially expands the applicability of CM by simply adding the CM information to the CM broadcasting system. The stored CM information is reusable when the program guide is displayed, increasing the chance of CM reproduction. This is basically acceptable for the sponsors. Thus, coexistence of the program guide and CM is appropriately realized.

Eighth Embodiment

[0158] An eight embodiment is explained based on a system handling a sub program of commercial (CM) in the same manner as in the seventh embodiment. FIG. 43 is a block diagram showing the arrangement of a program information producing apparatus 500 in accordance with the eighth embodiment of the present invention. The program information producing apparatus 500 comprises a program information producing section 50 producing program information, a CM positional information producing section 57 producing CM positional information, and a transmitting section 52 transmitting both of the program information and the CM positional information produced from the program information producing section 50 and the CM positional information producing section 57. FIG. 32 shows an event information table including program name, broadcast time, recording fee (with or without CM skip), playback fee with CM fast forwarding and other fees for each program. A charge information producing section 56 produces the information relating to the fees. The produced charge information is added to the program information. The CM positional information includes broadcast time of each CM, as shown in FIG. 33.

[0159]FIG. 44 is a block diagram showing a receiving apparatus 100 in accordance with the eighth embodiment of the present invention. When an ordinary program is recorded, the receiving apparatus 100 operates in the following manner.

[0160] {circumflex over (1)} A receiving apparatus 1 receives the program information. A program information storing section 2 stores the received program information. A program guide display section 6 displays a program list for recording reservation with reference to the program information (refer to FIG. 34). The CM positional information received by the receiving section 1 is stored in a CM positional information storing section 18.

[0161] {circumflex over (2)} The viewer makes a decision as to recording of the CM (refer to FIG. 35). According to the disclosed example, a recording reservation is made for the “Alarm clock TV!” program with associated CMs.

[0162] {circumflex over (3)} The receiving apparatus refers to the program information and the CM positional information. FIG. 33 shows a CM positional information table including the CMs having broadcast times scheduled in the time slot of the “Alarm clock TV!” program.

[0163] {circumflex over (4)} A program recording section 19 starts recording the program.

[0164] {circumflex over (5)} When the viewer selects the “recording with CM” in the procedure {circumflex over (2)}, the program recording section 19 records the CMs together with the “Alarm clock TV!” program.

[0165] When the viewer selects the “recording with no CM” in the procedure {circumflex over (2)}, the program recording section 19 skips the CMs with reference to the CM positional information to record only the “Alarm clock TV!” program.

[0166] {circumflex over (6)} A charging section 21 calculates a charge amount with reference to the selection of the viewer and recording fees described in the program information. Timing or method of the charging procedure may be different in each charging system adopted. According to the example disclosed in FIG. 35, the charging section 21 charges 20 yen according to the fees shown in FIG. 32 as the viewer selected the “recording with CM” of the “Alarm clock TV!” program.

[0167] Although FIG. 33 shows the table of CM positional information, it is possible to use a code indicating that the CM is presently broadcasted. This code can be broadcasted as part of the audio and video data of the CM (for example, by describing it in a user data region according to the standard of MPEG, in the case of digital broadcasting services). It is preferable that the receiving apparatus receives such a code and performs the recording and non-recording processing of the CM according to the received code.

[0168] As described in the foregoing description, the eighth embodiment sets a plurality of charge ranks according to the recording or viewing type of the CM. Thus, it becomes possible to set a variety of charge ranks according to advertisement activities of the broadcasters. For example, the fee for the recording with no CM is expensive because no advertisement income is expected. Furthermore, such a charge system will effectively prevent the viewers from cutting the CM thoughtlessly by utilizing the CM positional information.

Ninth Embodiment

[0169] A ninth embodiment is explained based on a system handling a sub program of commercial (CM) in the same manner as in the seventh embodiment. FIG. 45 is a block diagram showing the arrangement of a program information producing apparatus 500 in accordance with the ninth embodiment of the present invention. The program information producing apparatus 500 comprises a program information producing section 50 producing program information, a CM positional information producing section 57 producing CM positional information, and a transmitting section 52 transmitting both of the program information and the CM positional information produced from the program information producing section 50 and the CM positional information producing section 57. FIG. 36 shows an event information table including program name, broadcast time, CM playback frequency and others. A CM playback frequency information producing section 58 produces the CM playback frequency. The produced CM playback frequency is added to the program information. As shown in FIG. 33, the CM positional information includes broadcast time of each CM.

[0170]FIG. 46 is a block diagram showing a receiving apparatus 100 in accordance with the ninth embodiment of the present invention. When the viewer requests the recording of the “Alarm clock TV!” program, the receiving apparatus 100 operates in the following manner.

[0171] {circumflex over (1)} A program recording section 19 records the program described in the program information stored in a program information storing section 2. A CM recording section 22 records a CM described in the CM positional information stored in a CM positional information storing section 18.

[0172] {circumflex over (2)} Meanwhile, a playback order table producing section 26 produces a program recording management table (FIG. 37), a CM recording management table (FIG. 38), as well as a program CM playback order table (FIG. 39) and a CM playback frequency table (FIG. 40). The method of allocating a recording program file ID shown in the program recording management table (FIG. 37) and a recording CM file ID shown in the CM recording management table (FIG. 38) are dependent on the filing system of the storing apparatus in the receiving apparatus 100. Each stored program or CM is reproducible in response to entry of the corresponding file ID. The mandatory playback frequency shown in the CM playback frequency table (FIG. 40) agrees with the mandatory CM playback frequency described in the program information (FIG. 36).

[0173] {circumflex over (3)} A program playback section 25 reproduces recorded programs and CMs in accordance with an order described in the program CM playback order table (FIG. 39). In the CM playback frequency table (FIG. 40), the present playback frequency is incremented in response to each playback operation of the program, with an initial number 0 given when the table is produced. When the present playback frequency becomes identical with the mandatory playback frequency, the CM is no longer reproduced (i.e., skipped) during the playback of the program.

[0174] Although the above-described embodiment uses the table including the CM positional information, it is possible to use a code indicating that the CM is presently broadcasted. This code can be broadcasted as part of the audio and video data of the CM (for example, by describing it in a user data region according to the standard of MPEG, in the case of digital broadcasting services). It is preferable that the receiving apparatus receives such a code and performs the recording and non-recording processing of the CM according to the received code.

[0175] According to the above-described embodiment, the program information producing apparatus produces the program information including the mandatory CM playback frequency. However, the mandatory CM playback frequency may be a predetermined value which may be directly input into the receiving apparatus.

[0176] As described in the foregoing description, this embodiment surely performs the playback of the CM predetermined times. Thus, the broadcasters can provide the guaranteed CM playback system for each sponsor.

Tenth Embodiment

[0177] A tenth embodiment is explained based on a system handling a sub program of commercial (CM) in the same manner as in the ninth embodiment. The program information producing apparatus 500 of the ninth embodiment is directly applicable to the tenth embodiment.

[0178]FIG. 47 is a block diagram showing a receiving apparatus 100 in accordance with the tenth embodiment of the present invention. The receiving apparatus 100 operates in the following manner.

[0179] {circumflex over (1)} A program CM recording section 28 records a program described in the program information stored in a program information storing section 2 (as one stream).

[0180] {circumflex over (2)} In the same manner as the procedure {circumflex over (1)}, a program CM management table producing section 30 produces a program CM recording management table (FIG. 42), a CM position table (FIG. 41) and a CM playback frequency table (FIG. 40) with reference to the CM positional information stored in the CM positional information storing section 18. In the tables, the meaning of file IDs and the mandatory playback frequency are defined in the same manner as in the ninth embodiment.

[0181] {circumflex over (3)} A program playback section 25 reproduces a recorded program with reference to the program CM recording management table (FIG. 42). In the CM playback frequency table (FIG. 40), the present playback frequency is incremented in response to each playback operation of the program, with an initial number 0 given when the table is produced. When the present playback frequency becomes identical with the mandatory playback frequency, the CM is no longer reproduced (i.e., skipped) with reference to the CM position table (FIG. 41) during the playback of the program.

[0182] When the program information includes “playback fee with CM fast forwarding”, “viewing fee with CM”, and “viewing fee with CM skip” as shown in FIG. 32. In the receiving apparatus 100 (FIG. 46) of the ninth embodiment and the receiving apparatus 100 (FIG. 47) of the tenth embodiment, the charging section 21 calculates a charge amount with reference to the viewing pattern.

[0183] According to the above-described eighth to tenth embodiments, the receiving section of the receiving apparatus receives the program information and CM positional information. However, it is possible to use other appropriate media, such as FD and DVD, for storing and transmitting the program information and others, or it may be possible to use a terminal having the capability of storing the same.

[0184] In the explanation of the above-described eighth to tenth embodiments, operation of the broadcast center is omitted. However, it should be understood that the program information is produced from the program schedule information sent from the audio/video and program information organizing system 1002 shown in FIG. 73. If the audio/video and program information organizing system is not provided, it will be possible to produce the program information from the program schedule information in the program information producing apparatus.

[0185] According to the above-described embodiment, the program information producing apparatus produces the program information including the mandatory CM playback frequency. However, the mandatory CM playback frequency may be a predetermined value which may be directly input into the receiving apparatus.

[0186] As described in the foregoing description, this embodiment surely performs the playback of the CM predetermined times. Thus, the broadcasters can provide the guaranteed CM playback system for each sponsor.

Eleventh Embodiment

[0187]FIG. 50 is a block diagram showing a program information producing apparatus 500 in accordance with the eleventh embodiment. The program information producing apparatus 500 comprises a message timing information producing section 59 which produces message timing information. The message timing information determines a timing according to which the receiving apparatus outputs a message about the next program. The produced message timing information is added to the next program information. A next program information producing section 60 produces next program information during the broadcasting of a present program. The next program information includes information about a program to be tuned in to during or after the broadcasting of the present program. The produced next program information is added to the program information. A program information producing section 50 produces a table of the next program information shown in FIG. 49 and sends it to a transmitting section 52. Regarding a method of multiplexing the transmitting data, the digital broadcasting services will realize a multiplexed data transmission by describing the data in a user data region according to the standard of MPEG or by utilizing a section-type table.

[0188]FIG. 51 is a block diagram showing a receiving apparatus 100 in accordance with the eleventh embodiment. The receiving apparatus 100 comprises a receiving section 1 which receives the next program information as well as the present program information during the display of the present program. A message output section 32 outputs a message shown in FIG. 48 on the screen of a TV monitor 10 during or after the broadcasting of the present program. This message is for asking whether the viewer selects the next program or continues watching the same program. When the viewer selects the next program, a tuning switch section 33 tunes in to the next program described in the next program information. A program display section 8 produces the audio and video data of the next program.

[0189] When the next program information includes a message timing as shown in FIG. 49, the message output section 32 outputs the message at the designated timing.

[0190] Adding the message timing to the next program information as shown in FIG. 49 is effective to control the display timing of the message so as not to overlap with important announcement or advertisement provided in the program.

[0191] Although the example shown in FIG. 48 shows only one program, it is possible to display a plurality of next programs. In this case, the screen display of FIG. 48 will be slightly modified to allow the viewer to select a favorite program among the plurality of programs.

[0192] Describing the next program information is effective for the broadcasters selectively using a plurality of channels for broadcasting a same program, such as a highschool baseball telecast. For example, the next program information can be effectively used when the program is switched from the present channel to other channel due to organizing reasons of the programs, or when the broadcaster asks viewers to transfer to the other channel upon completion of the scheduled broadcast time in the present channel.

[0193] The present digital broadcast services generally define theoretical channels to let the viewers watch the same channel continuously. In the display of program guide, the program guide generally includes a plurality of channels, each channel including a plurality of time slots. However, if the concept of such channels is eliminated, or when the number of programs simultaneously broadcasted is varied, it will be difficult for the viewers to smoothly select a next program after finishing the viewing of the present program. In other words, it will be difficult for the receiving apparatus to appropriately tune in to the next program. However, the above-described eleventh embodiment solves these problems by providing the next program information. Thus, the viewer can smoothly select the next program. The receiving apparatus will have no dead time during which no channel is tuned.

[0194] The above-described eleventh embodiment can be applied to an emergency broadcasting. Although it may be possible to use network information describing reference information for an emergency broadcasting program, the eleventh embodiment makes it possible to set the reference information for the emergency broadcasting for each program. Thus, for the broadcasters who utilize no network information, it becomes possible to perform the emergency broadcasting based on their own judgement.

[0195] The above-described eleventh embodiment uses a screen display for letting the viewers know the message that the next program information is added to the program information. However, in the playback of a recorded program, such a message may not be displayed to perform the automatic tuning in to the next program. Alternatively, it may be possible to arrange the setting to ask the viewers as to whether they accept the automatic tuning function or not.

[0196] According to the above-described eleventh embodiment, the receiving section of the receiving apparatus receives the program information. However, it is possible to use other appropriate media, such as FD and DVD, for storing and transmitting the program information, or it may be possible to use a terminal having the capability of storing the same.

[0197] In the explanation of the above-described eleventh embodiment, operation of the broadcast center is omitted. However, it should be understood that the program information is produced from the program schedule information sent from the audio/video and program information organizing system 1002 shown in FIG. 73. If the audio/video and program information organizing system is not provided, it will be possible to produce the program information from the program schedule information in the program information producing apparatus.

Twelfth Embodiment

[0198] A twelfth embodiment provides a program guide whose content is variable in accordance with viewer's selection of a channel. FIG. 52 is a block diagram showing the arrangement of a program information producing apparatus 500 in accordance with the twelfth embodiment of the present invention. The program information producing apparatus 500 comprises a program information producing section 50 produces common program information for all of broadcasters as well as uncommon program information relating to exclusive channels provided by individual broadcasters. The produced program information is sent to a transmitting section 52. The common program information includes a table including overall data of the network (FIG. 60) or a table indicating the correlation between a broadcaster and channels (FIG. 61). The common program information is included in every TS (transport stream) signal. The uncommon program information includes a program broadcast schedule of each channel (FIG. 62) or channel information (FIG. 63). The uncommon program information is included in only the TS signal of a service channel of a related broadcaster (FIG. 64).

[0199]FIG. 53 is a receiving apparatus 100 in accordance with the twelfth embodiment of the present invention. The receiving apparatus 100 comprises a program information processing section 5 refers to the tuning condition of a tuning section 11 in response to viewer's request of displaying the program guide. A program guide display section 6 displays a program guide including the uncommon program information with reference to the TS signal of the channel selected by the viewer. For example, it is assumed that the viewer watches a program broadcasted in the channel of service_ID=4 (which is included in the TS signal of TS_ID=30 according to FIG. 64). From the correlation table of FIG. 61, it is understood that the viewer watches a program of “Ryukun TV” which corresponds to a “B” station in FIG. 64. Thus, if the viewer requests the display of program guide, the program guide display section 6 displays a program guide including program information of the specified channel of service_ID=4 as well as program information of other channels of service_ID=5, 6, 7, 8, and 9 with reference to the information of FIGS. 62 and 63.

[0200] With this arrangement, it becomes possible to switch the content of the displayed program guide in accordance with the viewing condition of the viewer (i.e., in response to viewer's selection of a channel in this embodiment). Furthermore, producing the correlation table according to this embodiment makes it possible to display a program guide of another channel having a different transport stream but provided by the same broadcaster.

Thirteenth Embodiment

[0201] A thirteenth embodiment provides a system wherein the program information includes related data of a program to be reserved by a receiving apparatus. More specifically, a program (e.g., program number 10) includes the program information related data as well as audio and video data. The program information related data is produced by a relevant information producing section 51 of the program information producing apparatus 500 shown in FIG. 52. The produced program information related data is transmitted in the form of MPEG2 private section data. FIG. 54 shows an example of a program component arrangement (PMT) including the MPEG2 private section data. This example includes component PIDs, according to which 102 is allocated to the program information related data. FIG. 55 shows details of the program information related data which is referred to according to the component PID=102.

[0214] A sixteenth embodiment of the present invention provides a system producing both analog BS information and digital BS information. FIG. 70 is a block diagram showing the arrangement of a program information producing apparatus 500 in accordance with the sixteenth embodiment of the present invention. In the program information producing apparatus 500, a link information producing section 61 produces analog program information involving program link information describing the relationship to a relevant digital program. For example, an analog program may be identical with a digital program in program name and broadcast time but different in viewing fee. In such a case, the different portion is described as information other than program link information. FIGS. 65 and 66 show examples of digital BS program information and analog BS program information, respectively. For example, in the analog BS program information shown in FIG. 66, an analog BS program identified by program_ID=230 is linked with a digital BS program having program_ID=30 which corresponds to the “Alarm lock TV!” program shown in the digital BS program information shown in FIG. 65. The analog BS program (program_ID=230) is identical with the digital BS program (program_ID=30) in program name, broadcast name and program duration but different in viewing fee. Thus, the viewing fee is described in the analog BS program information shown in FIG. 66. In other words, when the same information is described in the digital BS program information, the analog BS program information simply refers to it. Two kinds of program information data are transmitted through the digital BS service.

[0215]FIG. 71 is a block diagram showing the arrangement of a receiving apparatus 100 in accordance with the sixteenth embodiment of the present invention. In the receiving apparatus 100, a program guide display section 6 displays a program guide of a linked channel with reference to the received program information. FIG. 67 shows details of the displayed program guide, wherein the program name “Alarm clock TV!” is displayed based on the information from the digital BS program information. It is possible for the program guide display section 6 to display both an analog BS program guide and a digital BS program guide simultaneously on the screen, as shown in FIG. 72.

[0216] When the viewer selects the “Alarm clock TV!” from the program guide shown in FIG. 67 and watches the same served from the analog BS, a message output section 32 displays a message that the same program is broadcasted through the digital BS (using a small space on the screen as shown in FIG. 68). It is possible to display the viewing fees different between the digital BS and the analog BS as such information is obtainable from the program information. When the viewer selects “stay on analog”, the message disappears from the screen and the analog BS program is continuously displayed. When the viewer selects “transfer to digital”, a tuning switch section 33 tunes in to the designated channel with reference to the digital BS program guide.

[0217] As a modification of the above-described sixteenth embodiment, it may be possible to skip the display of the message and automatically tune in to the designated channel. According to the above-described sixteenth embodiment, the linked programs are scheduled in the same time slot. It is however possible to link any programs scheduled in different time slots. In this case, the broadcast time is included in the program link information.

[0218] The linked channels may be completely identical in their content. FIG. 69 shows the channel link information used when the program organization is identical, which is produced by the link information producing section 61. FIG. 69 shows that an analog channel of BS 30 has the same content as that of the linked channel (service_ID=300) of the digital BS. When the viewer requests the display of the analog BS program guide, the program guide display section 6 displays the analog BS program guide with reference to the program information of the digital BS in the same manner as the display of the linked program.

[0219] Furthermore, according to the above-described sixteenth embodiment, the receiving section of the receiving apparatus receives the program information. However, it is possible to use other appropriate media, such as FD and DVD, for storing and transmitting the program information, or it may be possible to use a terminal having the capability of storing the same.

[0220] In the explanation of the above-described sixteenth embodiment, operation of the broadcast center is omitted. However, it should be understood that the program information is produced from the program schedule information sent from the audio/video and program information organizing system 1002 shown in FIG. 73. If the audio/video and program information organizing system is not provided, it will be possible to produce the program information from the program schedule information in the program information producing apparatus.

[0221] As described above, the sixteenth embodiment produces the program information describing the linkage or correlation between different networks. Thus, the sixteenth embodiment allows the viewers to check the difference between the linked channels in their program contents, fees and qualities when the same program is broadcasted in both analog and digital channels through the simulcast service.

[0222] As apparent from the foregoing description, the first embodiment of the present invention makes it possible to display a program guide including a personal channel consisting of the programs selected according to the search condition given from the viewer. This arrangement is helpful for the viewers in selecting favorable programs from numerous programs receivable by his/her receiving apparatus. Furthermore, as an independent channel is assigned to the searched programs, the viewers can continuously watch the favorable programs without changing the channel. Providing the display of program fees is effective to facilitate the program selection. Thus, the first embodiment of the present invention improves the conspicuousness of the program guide.

[0223] Furthermore, the second embodiment of the present invention allows the viewer to modify the program guide through a manual operation when the program guide does not include any favorable program. Thus, it becomes possible to reschedule the personal channel.

[0226] Furthermore, the fifth embodiment of the present invention reduces the size of the program video in response to a viewer's request and displaying the program guide in a given space on the screen. Thus, the viewers can watch the program guide without interrupting the viewing of the program.

[0227] Furthermore, the sixth embodiment of the present invention makes it possible to provide the program guide capable of displaying a sponsor name paired with a program name. This is preferable in that displayed program guide does not substantially reduce the viewer's chance of watching sponsor name or sponsor information.

[0228] Furthermore, the seventh embodiment of the present invention substantially expands the applicability of CM by simply adding the CM information to the CM broadcasting system. The stored CM information is reusable when the program guide is displayed, increasing the chance of CM reproduction. This is basically acceptable for the sponsors. Thus, coexistence of the program guide and CM is appropriately realized.

[0229] Furthermore, the eighth embodiment of the present invention sets a plurality of charge ranks according to the recording or viewing type of the CM. Thus, it becomes possible to set a variety of charge ranks according to advertisement activities of the broadcasters. For example, the fee for the recording with no CM is expensive because no advertisement income is expected. Furthermore, such a charge system will effectively prevent the viewers from cutting the CM thoughtlessly by utilizing the CM positional information.

[0230] Furthermore, the ninth and tenth embodiments of the present invention surely perform the playback of the CM predetermined times. Thus, the broadcasters can provide the guaranteed CM playback system for each sponsor.

[0231] Furthermore, the eleventh embodiment of the present invention produces the next program information to be tuned in to during or after the broadcasting of the present program. The produced next program information is displayed on the screen of the receiving apparatus so as to encourage the viewer to select a favorable one.

[0232] Furthermore, the twelfth embodiment of the present invention makes it possible to switch the content of the displayed program guide in accordance with the viewing condition of the viewer. Furthermore, producing the correlation table according to this embodiment makes it possible to display a program guide of another channel having a different transport stream but provided by the same broadcaster.

[0233] Furthermore, the thirteenth embodiment of the present invention transmits the program information related data in synchronism with the broadcasting of a program. This program information related data is used for reserving the program Thus, it becomes possible to realize both the program guide display and the program reservation in accordance with the viewer's watching program. Furthermore, it is possible to include the control data of the program guide display in the program information related data. This allows the center system to precisely control the display of program guide.

[0234] Furthermore, the fourteenth embodiment of the present invention produces the program information related data including the instruction of the program guide display and the list of channels to be selected by the receiving apparatus. This allows the viewers to select a program among channels relating to the viewer's watching program.

[0235] Furthermore, the fifteenth embodiment of the present invention produces the program information related data including the list of channels to be promoted as well as the instruction of the program display in synchronism with the broadcasting of a program. This makes it possible to realize the promotion using a display screen consisting of dissected videos of the programs of other channels.
